Abstract

The invention provides a bamboo fiber reinforced styrene-free unsaturated polyester composite material and a preparation method thereof. Acetylene and 3-hydroxymethyl phenylpropane are taken as raw materials, a monomer with multiple double bonds, namely 1, 1, 1-trivinyl methoxyphenylpropane is synthesized under alkaline conditions and used as a reaction solvent of unsaturated polyester, and the composite material is prepared by taking bamboo fiber as a reinforcing body. The unsaturated polyester used by the composite material prepared by the preparation method provided by the invention does not contain the carcinogenic reaction solvent, namely styrene, thereby having the characteristics of environmental friendliness and low cost; the prepared composite material has the advantages of very high tensile strength, flexural strength, flexural modulus and impact strength.

Description

technical field [0001] The invention belongs to the technical field of natural plant fiber-reinforced resin composite materials, and in particular relates to a bamboo fiber-reinforced styrene-free unsaturated polyester composite material and a preparation method thereof. Background technique [0002] Unsaturated polyester (UPE) is the most used resin variety in glass fiber reinforced resin composite materials. UPE resin has good mechanical properties and manufacturability, but a large amount of volatile styrene is used as diluent and crosslinking agent in the preparation process, and the resulting air pollution has attracted great attention. In 2011, the U.S. Department of Health and Human Services officially listed styrene and respirable fiberglass as carcinogens. Therefore, for the fiber-reinforced resin-based composite material industry, it is necessary to seek new reinforcements to minimize the use of glass fibers, and at the same time take measures to reduce the amount...
